Here is the geometric interpretation (see circumscribed regular polygons):
- begin with a unit circle;
- circumscribe an equilateral triangle and then circumscribe a circle;
- circumscribe a square and then circumscribe a circle;
- circumscribe a regular pentagon and then circumscribe a circle;
- etc.
The circles have radii which converge to this value.
The reciprocal of the polygon-circumscribing constant gives the polygon-inscribing constant (A085365) (see inscribed regular polygons)
- 1 / 8.700036625208... = 0.1149420448532...
